Abstract
A method for manufacturing an ink cartridge includes the step of connecting a film or a pair of films to a frame. The films and the frame define an ink chamber therein, and the ink cartridge includes the films and the frame. The method also includes the step of positioning a patterned member adjacent to the films. The patterned member includes a first pattern, and the first pattern includes a first portion and a second portion which is raised with respect to the first portion. Moreover, the method includes the step of forming a second pattern corresponding to the first pattern on the films by generating a pressure differential between a pressure inside the ink chamber and a pressure outside the ink chamber, in which the pressure differential draws the films into contact with the first pattern.
Claims9
A method for manufacturing an ink cartridge comprising the steps of:
- connecting at least one film to a frame, wherein the at least one film and the frame define an ink chamber therein, and the ink cartridge comprises the at least one film and the frame;
- positioning a patterned member adjacent to the at least one film, wherein the patterned member comprises a first pattern, and the first pattern comprises a first portion and a second portion which is raised with respect to the first portion;
- and
- forming a second pattern corresponding to the first pattern on the at least one film by generating a pressure differential between a pressure inside the ink chamber and a pressure outside the ink chamber, wherein the pressure differential draws the at least one film into contact with at least a portion of the first pattern, and wherein the step of forming the second pattern comprises the substep of reducing the pressure outside the ink chamber.
